"She's going to take her station in Duck's Creek," said Ben.
Upon hearing this, Harry's expectations fell again.
"It's no use," he exclaimed. "Charley Sheldon knows too much for us."
"Not a bit," said Frank. "This arrangement is only for to-night. When we get up in the morning, we shall find the boats all out in the river."
This immediately reassured Harry; and, after watching the Sampson until she disappeared in Duck's Creek, he led the way to the house.
After supper, as soon as it began to grow dark, they proceeded to put their plans into execution; but, before they started, Frank said,
"Now, boys, we must watch and see how the trick takes, for I know that there are spies now around that boat-house. As soon as we get the sham provisions into the boat, one or two of us had better slip down into the willows behind the wharf, and see what course things are going to take."
"Well," said Harry, "suppose you and Bill act as spies."
"Agreed. Come on, but don't act as if you suspected anything."
And he led the way toward the boat-house.
